METHOD OF AND APPARATUS FOR ORDERING TOBACCO.

SPECIFICATION forming part of Letters Patent No. 535,175, dated March 5, 1895. Application filed November 6, 1894. Serial No. 528,041. (No model.)

To all whom it may concern:

Be it known that I, CHARLES W. SCHWARTZ,

Jr., a citizen of the United States, residing at Germantown, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Methods of and Apparatus for Ordering Tobacco, of which the following is a specification.

My invention relates to a method of and apparatus for ordering tobacco.

The principal objects of my invention are, first, to provide a simple and effective method of hastening the ordering of tobacco so that any tendency to scorching or scalding of the same is entirely prevented and the tobacco rendered sweet in taste and subsequent handling permitted with perfect safety and without fear of crushing the leaves thereof; second, to provide an efficient method of ordering tobacco by circulation and recirculation,

which consists in presenting air of one temporature to water of a different temperature in a chamber to cause the latter to be com bined so as to produce a humid atmosphere which is forced into the presence of the tobacco absorbing the humidity of the air and again conveying the same into the presence of water to revivify the same and presenting to the tobacco to effect the complete orderingthereof, and, third, to provide suitable apparatus for the conduct of the method of ordering tobacco of-my invention.

My invention stated in general-terms comprises a method of ordering tobacco by cir- 3 5 culation and recirculation which consists in presenting air of one temperature in the path of water of a different temperature to produce a humid atmosphere and presenting to sus pended tobacco in such manner as to cause an absorption of the humidity of the air thereby and conveying the air deprived of its humidity to water to supply the same with humidity and presenting again to the tobacco to effect complete or thorough ordering of the same.

My invention further consists in the method of ordering tobacco, of forcing air of one temperature into the presence of water of higher temperature to produce a humid atmosphere and presenting to tobacco, which absorbs humidity therefrom, then presenting to water to revivify the same and under pressure forcing again into the presence of the tobacco to effect the complete ordering thereof.

My invention further consists of the method of ordering tobacco by circulation and recirculation, which consists in subjecting air brought to a low temperature into the presence of water maintained at a high temperature to produce a humid atmosphere and presenting continuously to tobacco and successivelv to water topermit of absorption in the one instance by the tobacco of the humidity of the air and in the other of the supply of the air with humidity so as to again present 6 to the tobacco to effect the complete ordering thereof.

My invention further consists of suitable apparatus for the conduct of the method of ordering tobacco of myinvention,constructed and arranged in substantially the manner hereinafter described and claimed.

The nature and general features of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which Figure 1, is a central vertical sect on through one form of apparatus embodying features of my invention, and such as in prac- 8o tice has been found well adapted for the conduct of the method of ordering tobacco of my invention. Fig. 2, is a longitudinal section through the apparatus on the line 0 c-0c, of Fig.

1. Fig. 3, isa vertical central section through a modified form of apparatus to that of Fig.

1, for carrying into effect the method of my invention. Fig. 4, is a vertical longitudinal section on the line yy, of Fig. 3. Fig. 5, is

a vertical central section through a still fur- 9o ther modified form of apparatus of my invention; and Fig. 6, is a vertical longitudinal section on the line z-z, of Fig. 5.

Referring to the drawings A, is a housing provided with internal chambers 00 and a, 5 partially separated from each other by a partition a with reference to Figs. 1 and 2, of the drawings. 'In the partition a at the upper portion thereof is provided an opening, into which is mounted a propeller fan or agiroo tating device B, mounted on a cross shaft b which extends through the housing A, and carries a pulley b, and abelt b for effecting the rotation of the said fan or agitating device B.

0. is an openingin the lower portion of said partition (1 for a purpose to be presently explained.

In the bottom of the chamber a, is mounted an oblong trough or tank 0, adapted to contain water introduced into the same by means of a spigot 0, having a stop-cock c. In the bottom of the trough or tank 0, is provided a coiled pipe 0 for heating thewater therein in such manner as that the same will be maintained at a higher temperature than the air caused to circulate around or about the water of this trough 0. Above the tank or trough O, is'provided a cooling or refrigerating coiled or other appliance C, for reducing the temperature of the air caused to circulate in the chambers of the housing A, and so that it may be maintained at such a temperature as to intimately blend or combine with the water of a higher temperature traveling in the path thereof and thereby producing the required humid atmosphere for presenting by circulation and recirculation to the tobacco to be absorbed by it in whole or in part to dampen and order the same.

D, is a truck adapted to be introduced into the chamber a, and provided with cross rods d, for supporting bunches of tobacco D therefrom.

d, are rails over which the truck is moved into and out of thehousing A, through a door a provided in one of the side or end walls of the same.

In the operation of the apparatus of Figs. 1 and 2, the air is forced by means of the propeller or agitating device B, into the chamber a, and the temperature of the water in the chamber a, being raised by means-of the steam coil 0 so as to cause the air therein freed from the agitating influence of said device D, and in a more or less calm state and brought to and maintained at a lower temperature than the waterby the cooling orrefrigerating appliance O, in the chamber a, and until it is caused to associate with the water to produce a humid atmosphere in the chamber a, of the housing A, and which after the starting up of the apparatus is continuously conducted through the chambers a and a, into the presence of the tobacco D in the latter chamber a',,and the humidity of the air is absorbed by the tobacco suspended from the truck D, therein and under. the influence of the propeller fan or agitating device B, the air having the humidity dissociated therefrom is carried back again into the chamber a, where it becomes again a humid atmosphere and is conveyed into the presence of the tobacco to effect first the moistening or dampening of the surface or body thereof and by continuous circulation and recirculation of the air supplied with moisture, complete ordering of the tobacco.

With reference to Figs. 3 and 4, the apparatus issubstantially the same as that of Figs. 1 and 2, with the following exceptionsz-The blowing or agitating device B, in the present instance, is provided with a transverse conduit b extending substantially the width of the housing A, and connected therewith are longitudinal pipes or conduits b, on each side provided with depending perforated pipes 6 as clearly illustrated in Fig. 4. Within the housing A, are mounted two trucks D and D, on rails d, secured to the floor thereof, and with a water tank or trough 0, located in a central chamber a and havinga heating coil extending through the tank or trough for not only heating, but also maintaining the water therein at a diflierent temperature from that of air caused to circulate through the internal chambers of the housing A, and becoming associated with the water to produce a humid atmosphere, for being presented to the tobacco in bunch or other form suspended from the trucks D and D, as fully illustrated in Fig. 3.

127, is a pipe or conduit located beneath the roof of the housing on theinside thereof and connected with the rear of the blowing device B. This'pipe or conduit bflis'provided with a series of depending inlets b and at the left hand end thereof is provided a large inlet or throat If, for sucking air into the same deprived of its moisture or humidity through its absorption by the tobacco and which air is also drawn through the series of inlets 11 of said conduit 11 thereby and conducted rearwardly'in-to the blowing device B, and by which latter means the air is again conveyed through the transverse conduit b and then longitudinally and downwardly through the perforated depending pipes or conduits and b in such manner as that the presence of the air of one temperature from said perforated pipes 19 on both sides of the interior of the housing, then in a more or less calm state or condition, will be brought into the path of water in the tank or vat O, of a different temperature, thereby receiving moisture therefrom and thus converting the air into a humid atmosphere which is presented by circulation and recirculation to the tobacco suspended from the trucks D and D, to eifect first moistening of the body or surface of the tobacco and then complete ordering of the same.

It maybe here remarked that the cooling or refrigerating appliance may be in the nature of a sprayer or any other somewhat similar means to be further explained to reduce the temperature of air circulating in and about the interior of the housing below the temperature of the heated water of the tank or trough C.

With reference to Figs. 5 and 6, the apparatus therein differs from that herein-before described in the following particulars:Instead of providing on the interior of the housing A, a series of depending perforated tubes b connected with pipes or conduits b and with a main conduit 19 in which air is conducted therethrough by means of a blowing device B, propeller fans B, as illustrated in Figs. 1 and 2, are employed in the top of the housing and the air is forced therefrom and thereby in different directions as indicated by the arrows in Fig. 5, and in a more or less calm state by this time, into the presence of water maintained at a different temperature from the air, so that the latter may effectually absorb the water and thus create a humid atmosphere for presenting to the tobacco supported from the trucks D and D, in the chambers a and a, which are separated from each other by means of partitions a and at These partitions are provided with staggered openings, as clearly illustrated in Fig. 5. The cooling or refrigerating appliance for reducing the temperature of circulating air in this instance is in the nature of a water sprayer or atomizer 0 as fully illustrated in Figs. 5 and 6. In other respects the apparatus is the same as that hereinbefore fully explained and the devices associated with the apparatus operate in the same manner as they do with reference to Figs. 1 to 4, of the drawings.

It will be manifestly obvious to those skilled in the art to which my invention appertains that still further modifications as to details of construction of the apparatus and arrangement of the devices connected therewith may bemade, without departing from the spirit and scope thereof; and hence I do not wish to be understood as limiting myself to the precise arrangements of all the parts of the apparatus as illustrated; but

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The method of ordering tobacco, which consists in continuously presenting air of one temperature in a chamber to water of another temperature to produce a humid atmosphere, conveying the same into the presence of tobacco to effect dampening thereof, and cansing successively the air deprived of its humidity to be revivified and again presented to the tobacco to effect ordering thereof, substantially as described.

2. The method of ordering tobacco, which consists in forcing air into the presence of water of a temperature difiering from the air to become associated therewith by producing a humid atmosphere, conveying the'same to tobacco which absorbs the humidity thereof, conducting the air deprived of its humidity to the water to revivify the same and then presenting the air recharged with moisture to the tobacco to effect ordering thereof, substantially as described.
